ABSTRACT:
A dynamic type RAM is provided wherein the level of a precharge control signal supplied to a gate of a precharge MOSFET to precharge complementary data lines to a half level is made the half level during a period from the memory access until the selection of the word line, at the latest. Also, the precharge control signal, corresponding to a memory mat selected according to establishing of an address, is set to a low level, while the precharge control signal corresponding to a non-selective memory mat is set to a high level.
